2000 Jeep Cherokee Sport ... dashboard oil pressure gauge suddenly max out. Engine is not overheating at all or otherwise having any problems. Have been driving it for a few days and have not noticed any problems. I am making an assumption if there was a problem with oil circulation, the engine temp would be high or would vary a bunch ... but I am not seeing that. Since it was sudden, I think it may be the unit (dont know what its called) that is next to the oil filter that reads the oil pressure. 2 questions ... 1 Do you agree and if not, your opinion. 2 If it is that unit, when changing it out, what do I put on the threads when reinstalling a new unit ?[/quote:168fbf5c8d]

Yes, it is the "Oil pressure sending unit". Yes, it is right next to the oil filter, and during normal oil changes gets bumped and you are seeing the result of that. There are "no" adverse effects to having oil pressure too high, only too low. So don't even worry about it. Next time you need your jeep serviced ask the mechanic too adjust the sending unit. If he doesn't know what you are talking about, go somewhere else...
